Product Overview
Tag | N/A |
Host Species | Human |
Background | IFN-alpha 1b is expressed by macrophages, IFN-alpha 1b has antiviral activities and stimulates the production of two 56: a protein kinase and an oligoadenylate synthetase. |
Description | Interferon-alpha 1b Human Recombinant expressed in E.Coli is a single, non-glycosylated, polypeptide chain containing 166a.a. and having a molecular weight of 19392 Dalton.The Interferon-alpha 1b gene was obtained from human leukocytes.The IFN-a 1b is purified by unique purification methods. |
Source | E.coli |
AA Sequence | The sequence of the first five N-terminalaa was determined and was found to be Cys-Asp-Leu-Pro-Glu. |
Purity | >96.0% as determined by:(a) Analysis by RP-HPLC.(b) Analysis by SDS-PAGE. |
Endotoxin | <1.0 EU per μg by the LAL method. |
Bioactivity | The specific activity as determined in a viral resistance assay using Bovine |
Formulation | Lyophilized from a 0.2µm filtered solution (50ug/ml) in PBS, pH 7.4, containing 4% mannitol and 1% HSA. |
Stability | Recombinant protein is stable for 12 months at -70°C |
Usage | For Research Use Only |
Storage | Lyophilized Interferon alpha 1b although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution IFN-alpha 1b should be stored at 4°C between 2-7 days and for future use below -18°C.For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).Please prevent freeze-thaw cycles. |
